** Place on component classes to explicitly use a named template file.** By default, 'efanXtra' looks for an efan template with the same name as the component class. @FacetMeta { inherited = true}facet class TemplateLocation {** Use to explicitly set the location of the efan template. The Url may take several forms:** - if fully qualified, the template is resolved, e.g. 'fan://acmePod/templates/Notice.efan' ** - if relative, the template is assumed to be on the file system, e.g. 'etc/templates/Notice.efan' ** - if absolute, the template is assumed to be a pod resource, e.g. '/templates/Notice.efan'const Uri? url}** Place on 'abstract' base components to tell 'efanExta' not to treat it as a component. Example:** ** syntax: fantom** ** using afEfanExtra** ** @Abstract** const mixin MyComponent : EfanComponent { ... }** ** Because components are mixins, 'efanXtra' has no other way to differentiate between real components and base classes! facet class Abstract {}** Use to mark a component lifecycle method. Init render methods may take any number of parameters. Example:** ** syntax: fantom** ** @InitRender** Bool? initRender(Str x, Int y) { ... }** ** Param types may be nullable.facet class InitRender {}** Use to mark a component lifecycle method. ** Before render methods may optionally define a 'StrBuf' parameter. ** You can use this to change any part of the current rendering.** ** syntax: fantom** ** @BeforeRender** Bool? beforeRender(StrBuf output) { ... }** ** If the method returns 'false' then rendering is skipped and '@AfterRender' is called.facet class BeforeRender {}** Use to mark a component lifecycle method.** After render methods may optionally define a 'StrBuf' parameter. ** You can use this to change any part of the current rendering.** ** syntax: fantom** ** @AfterRender** Bool? afterRender(StrBuf output) { ... }** ** If the method returns 'false' then the lifecyle returns back to '@BeforeRender'.facet class AfterRender {}
